DRAFT RIGGING.

Application led February 4.-, 1924.

ITo all 107mm t may concern.:

Be it known that l, Brin-:s lV. Kiper., a citizen of the United States,residing at Baltimore, in the State of Maryland, have invented certainnew and useful Improvements in Draft Rigging; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such` as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to railway draft rigging and more particularly toan improved connection between. the yoke and coupler.

One of the principal features of the present invention is to provide aconnection between the yoke and coupler in which is provided arelatively large and increased bearing area for the key connecting saidelements while maintaining free angling movement of the coupler butt.

Another object ofthe invention consists in providing a very strong anddurable connection between the coupler and yoke, said connectionproviding a greater bearing area for the coupler key and involvingenlargements or projections arranged upon the inner opposed faces of theyoke arms adapted to cooperate with pockets or depressions formed inopposite sides of the coupler shank provided at the forward end of thecoupler key slot.

A. further object of the invention is to provide a railway draft riggingembodying a vertical yoke attachment in which opposite Haring walls ofthe hooded head are provided with inwardly extending reinforcingprojections arranged at the forward ends of the key slots and adapted toprovide increased `bearing area for the forward edge of the key, theshank of thev coupler being readily insertible between said projectionsand having cut away portions in which said projections may move uponangling of the coupler under service conditions.

lilith these and other objects in view, the invention further consistsin the combination, construction and arrangement of the several partshereinafterl set fort-h.

ln the drawings illustrating the invention, the scope whereof pointed`out in the claims:

Figure l is a view in horizontal section Serial No. 690,456.

of a railway draft rigging showing a yoke member and coupler constructedin accordance with the invention.

Figure 2 is a detail horizontal sectional view on an enlarged scalethrough the forward end of the yoke member and the shank of the coupler.

Figure 3 is a detail. vertical transverse sectional view on the line Bwlof Figure 2.

Referring to the drawings in which corresponding reference charactersdesignate similar parts in the several views, the numerals l-l indicatecenter sills or draft sills of the railway draft rigging, said draftsills being suitably spaced and provided with the front stop members 2and rear stop members 3 between which is interposed the cushioningmechanism diagrammatically illustratedby dot and dash lines. The forwardends of the draft sills are slotted, as at 4i, said slotsregisteringjwith slots 5 provided in the front stop members.

In the embodiment of the invention illustrated there is shown a verticalyoke 6 having a hooded end 7 into which is fitted the shank of thecoupler 8. While I have shown the invention as primarily designed forvertical attachments, it will be understood that the invention is notlimited to the construction set forth herein.

The hooded end of the yoke is provided with oppositelydisposed outwardlyflaring walls 9, each of said walls being slotted, as at 10, and havinginwardly extending enlargements or projections ll arranged at theforward ends of the slots. rPhe projections ll are designed to reinforcethe forward ends of the yoke and provide relatively large bearing areasagainst which the forward edge of the key l2 contacts on draft. Theprojections border the forward end of the key slots in the side walls ofthe yoke head, said projections extending slightly rearwardly of theforward end of the slot and continuing forwardly to the front of saidside walls.

The coupler, and more especially the shank thereof, is provided withdepressions or cut away portions 13 disposed upon opposite sidesthereof, said depressions being located adjacent the forward end of thekey slot l-i in the coupler and being generally shaped to conform to theprojections l1 with which latter they are designed to cooperate. Thedepressions or cut away portions 13 extend forwardly and rearwardly ofthe `front wall of the key opening or slot let and are designed toreceive the projections or enlargements 'l1 upon swinging movement ofthe coupler with respect to the yoke head.

yoke constructed in accordance with the present invention is capable ofreceiving a coupler of standard dimensions between the projections orenlargements 1l, it being observed that the spacing now maintainedbetween the inner opposed faces of the yoke arms and the adjacent sidesof the coupler is utilized `to provide for the increased bearing area,the adjacent portions of opposite sides of the coupler shank beingpocketed or depressed whereby an effective spacing of the yoke andcoupler is maintained. It will be observed that the rear bearing'face ofthe key slot let in the coupler overlics the depressed or eut awayportions 13 therein. The additional bearing areas formed on the projections 11 constitute continuations of the key bearing portions' of theslotted side walls in the yoke head, each additional bearing area beingarranged in alinement with the key bearing portion as now provided atthe forward ends of thekey slot in each yoke arm. y

Having thus described my invention, what I claimas new and desire tosecure by Letters Patent, is:

1. In a railway draft rigging, the combination with center sills, of acoupler having depressions in opposite sides thereof, a yoke, a keyconnecting the yoke to said coupler, and means on said yoke adapted toprovide relatively large and increased bearing areas for said key, saidmeans projecting inwardly of the yoke arms and capable of moving intothe depressions formed on the coupler.

2. In a railway draft rigging, the combination with car sills, of acoupler having depressions in opposite sides thereof, and a slotintersecting said depressions, a hooded yoke having opposite side wallseach of which is provided with an opening, a key extending through saidopenings and slot for connecting the yoke and coupler, the side walls ofthe hooded yoke being formed with inwardly extending reinforcingportions adjacent at least one end of the openings therein, saidinwardly extending portions providing relatively large hearing areas forthe forward edge of the key and capable of moving respectively into thedepressions in the coupler upon angling movement thereof.

In a railway draft rigging, the combination with carsills, of a couplerhaving an opening, a yoke having a hooded end, the opposite side wallsof which are slotted, means passing through said slotted walls andopening into the coupler for connecting the latter to the yoke, andmeans formed on said yoke adapted to provide an increased bearing areafor the means connecting the coupler and yoke, said last named meansbeing adapted to coact with adjacent portions (of the coupler forpermitting angling of the latter while providing for said increasedbearing area.

4. In a railway draft rigging, the combination with center sills, of acoupler having an opening, said coupler having opposite sides thereofformed with cut-away portions adjacent said opening, a yoke comprisingspaced arms having the forward ends thereof slotted, a key passingthrough said slotted forward ends and the opening in the coupler, saidforward ends of the yoke arms having portions adjacent said slot adaptedto form increased bearing areas for the key connecting the coupler andyoke, said portions being adapted to coact with the cutaway portions onsaid coupler.

In a railway draft rigging, the combination with center sills, a yokemember comprising spaced arms each having a slot at its forward end,projections formed on said yoke arms and extending inwardly thereof,said projections providing relatively large key bearing areas, a couplerinsertible between said yoke arms and projections, said coupler havingopposite faces provided with cut-away vportions adapted to coact withsaid projections and being provided with an opening disposed inalinement with the slots in the yoke arms, and a key connecting saidyoke and coupler, said key having portions contacting said relativelylarge bearing areas on said projections.

6. In a railway draft rigging, the combination with car sills, of a yokemember having spaced arms, each of said arms being slotted at itsforward end, a reinforcing projection formed on each yoke arm and e3;-tending inwardly thereof adjacent the slot in said arm, a couplerinsertible between said projections, said coupler having cutawayportions coacting with said projections and being formed with anopening, and means connecting said coupler and yoke, said means passingthrough the opening in the coupler and slots in the yoke arms and havinga bearing on said reinforcing projection. i

7. The combination with a slotted yoke. of a coupler provided with anopening and having opposite side portions adjacent said opening cut-awayat points opposite the forward ends of the slotted portions of said yoketo permit angling with respect to said yoke, and means passing throughsaid opening for connecting said coupler and yoke.

8. The combination with a yoke member comprising slotted arms, of acoupler provided With a shank having an opening, said shank beingprovided upon opposite sides thereof with depressions located adjacentthe forwards ends of said opening to provide Clearance between the shankand yoke, and a key connecting said coupler and yoke.

S). A yoke for railway draft rigging coinprising a hooded end havingoutwardly flaring side walls each formed with a slot, and reinforcingprojections disposed adjacent the forward ends of said slots andextending inwardly of the side walls, said projections having keybearingareas disposed in aline nient with the key bearing portions of saidslots.
